The adult worms are eliminated in 1-2 years, but the register of the longevity can reach some years. Harvard oftentimes addresses this issue. The sanguine loss is an important cause of ferropriva anemia, not only because of its frequency, but also because the diagnosis and the handling of the hemorrhagic injury are of great importance for the process of cure and welfare of the patient. With the purpose esteem the effect of the sanguine loss in the rocking of the iron, 1 ml of blood contains 0,5 approximately mg of iron. Thus assumed, a negative rocking can be configured with small loss of blood, as of 3 the 4 ml/dia (1,5 the 2 mg of iron). The gradual loss of iron, through the injury of the intestinal mucosa, caused for the espoliadora action of the parasite, causes the clinical picture of ferropriva anemia, what it can intensified depending on the degree of infection for the parasite, beyond ferric losses also has the proteinic loss. In the ancilostomtica anemia, the iron lack leads to the deficient production of hemoglobina.
Consequently, the oxygen transport becomes insufficient. In this manner, the organism cannot synthecize necessary proteins, in virtue of the lack of the element most important in its metabolism, the oxygen. The ferropriva anemia that if it installs in insidioso way has a parasitado organism, and generally it is decurrent of some reinfeces and this is the natural consequence of the environment where the individuals of low partner-economic classroom and the agricultural zone live. Although the blood spoliation occurs daily and in amounts until considerable, the supplies of iron of organism depletados of the carrying sick people of parasatism obtains to remain itself for period of relatively long time without showing any sintomatologia. This is detected when the lost blood due to infection, starts to intervene with the life of the patient. However, afeces of the digestive device can cause or aggravate the corporal deficit of iron, basically, for reducing the absorption.
